In what seems like an ever-revolving door of new CEOs, Yahoo appears to have landed a winner with its latest chief executive. Yahoo today announced that it snagged a high-profile executive from Google: 37-year-old Marissa Mayer. Mayer was one of the first females hired at Google way back in 1999 (she was the 20th employee hired), and rose to the position of Vice President of Local, Maps and Location Services.

As President and CEO of Yahoo, Mayer will be in charge of reviving/expanding the site's many properties including Yahoo! Finance, Yahoo! Sports, Yahoo! Mail, and Yahoo! Search.

"I am honored and delighted to lead Yahoo!, one of the internet's premier destinations for more than 700 million users," said Mayer. "I look forward to working with the Company's dedicated employees to bring innovative products, content, and personalized experiences to users and advertisers all around the world."

According to a report from the New York Times, Mayer resigned this afternoon from Google via telephone. Her first day at Yahoo begins tomorrow.
